1. An expansion tank system for a liquid cooling system, comprising:
a first chamber for receiving a coolant, the first chamber having a first coolant port;
a second chamber for storing a pressurized gas;
a first gas conveying device connected to the first chamber and the second chamber for conveying gas from the first chamber to the second chamber;
a second gas conveying device connected to the first chamber and the second chamber for conveying gas from the second chamber to the first chamber;
a first pressure sensor in fluid communication with the first chamber; and
a control unit connected to the first gas conveying device, the second gas conveying device and the first pressure sensor;
wherein the control unit is configured for controlling the second gas conveying device to selectively convey gas from the second chamber to the first chamber if a pressure measured through the first pressure sensor is below a predefined first threshold value, and for controlling the first gas conveying device to selectively convey gas from the first chamber to the second chamber if a pressure measured through the first pressure sensor is above a second threshold value.
